Blast Quarry
Extract three gems with two cross-blasts, one pick strike and one gas vent. Select a tool, then tap a cell. Blast must be planted in reachable empty air; it destroys every cell up to TWO steps in all four straight directions, passing through rock and gems. Hitting any unvented G gas ends the run. Vent safely empties one gas cell beside reachable air. Pick removes one adjacent rock or gem without a blast. Empty border cells are entrances; opened air connects new work sites. Plan one vent that makes both explosions safe, and reserve the pick for the remaining gem.
